Please help me as this new to me (was my Dad's) w123 and I get to know each other….

4 door sedan with ~160K miles) with 3 adults, 2 sets of hockey gear, highway miles, ambient temp ~70 degrees F, No A/C used.

highway travel ~70MPH

on longer uphills I'd see the temp climb to 95-100 degrees C (via stock coolant temp gauge) - never went higher….If I backed off a bit or the road leveled out the temp would fairly quickly drop to ~85 - 90 degrees C….When I say hills we're talking Vermont….some nice rollling hills sometimes going uphill for a couple of miles and maybe gaining a couple of thousand feet We're not talking colorado etc. with l-o-n-g passes with BIG elevation changes…..
